Primary reason for administering morphine to a client with a myocardial infarction:
To decrease oxygen demand
... [Show More] on the client’s heart.
Rationals: Morphine will also decrease pain and anxiety while causing sedation, but it is not primarily
given for those reasons.
What supplemental medication is most frequently ordered in conjunction with furosemide (Lasix)?
Potassium
Rationals: potassium loss occurs as a result of this diuretic.
How long after oral administration can the nurse expect to see digoxin's (Lanoxin) peak effect?
2 to 6 hours
RATIONALES: The peak effect of digoxin occurs 2 to 6 hours after an oral dose and 1 to 4 hours after an
I.V. dose. Digoxin's onset of action ranges from 30 minutes to 2 hours after an oral dose and from 5 to 30
minutes after an I.V. Dose.
The physician prescribes several drugs for a client with hemorrhagic stroke. Which drug order should the
nurse question?
Heparin sodium
RATIONALES: Administration of heparin, an anticoagulant, could increase the bleeding associated with
hemorrhagic stroke. Therefore, the nurse should question this order to prevent additional hemorrhage in the
brain. In a client with hemorrhagic stroke, dexamethasone may be used to decrease cerebral edema and
pressure; methyldopa, to reduce blood pressure; and phenytoin, to prevent seizures.
A client with a history of atrial arrhythmia is receiving propranolol (Inderal), 10 mg by mouth three times
per day. The nurse knows that propranolol inhibits the action of sympathomimetics ᄃ at beta1-receptor
sites. Where are these sites mainly located?
Heart
RATIONALES: Beta1-receptor sites are mainly located in the heart. Beta2-receptor sites are located in the
uterus, blood vessels, and bronchi.
A client is evaluated for hypertension. The physician prescribes atenolol (Tenormin), 50 mg by mouth
daily. Atenolol should have which therapeutic effect on the client?
Decreased cardiac output and systolic and diastolic blood pressure
RATIONALES: As a long-acting, selective beta1 blocker, atenolol decreases cardiac output ᄃ and systolic
and diastolic blood pressure; however, like other beta-adrenergic blocking agents, it increases peripheral
vascular resistance at rest and with exercise. Atenolol may cause bradycardia ᄃ, not tachycardia ᄃ.
After experiencing a transient ischemic attack (TIA), a client is prescribed aspirin, 325 mg by mouth daily.
The nurse should teach the client that this medication has been prescribed to:
reduce platelet agglutination.
RATIONALES: TIAs are considered forerunners of stroke ᄃ. Because a stroke may result from a clot in a
cerebral vessel, aspirin is prescribed to prevent clot formation by reducing platelet agglutination. A 325-mg
dose of aspirin is inadequate to relieve headache pain in an adult. Aspirin has no effect on the body's
